Abstract
The utility model relates to the field of medical instrument technology, especially a kind of adjustable monoplane pedicle nail, including movable sleeve, nail, jackscrew and arc pitman, arc pitman is placed in movable sleeve U-type groove, and the jackscrew for compressing arc pitman is equipped in movable sleeve, the limited block for making nail that can only do monoplane swing in movable sleeve is equipped in movable sleeve, the utility model can make arc pitman be bonded limited block completely, arc pitman is pushed down with jackscrew again, it can fix arc pitman is more firm, in addition the consistency in the direction of two adjustable monoplane pedicle nails of backbone different segment can be kept, a possibility that preventing arc pitman from generating slide bar.
Description
Technical field
The utility model relates to the field of medical instrument technology, especially a kind of adjustable monoplane pedicle nail.
Background technique
Internal fixation of spine technology has the meaning of milestone in the development of spinal surgery, is widely used in spinal disease, wound
The treatment of wound is the prerequisite training technical ability of spinal surgery doctor.The application of internal fixation of spine technology must have good
Anatomical basis and biomechanical knowledge.
China also had more and more modern Internal fixation technologies of orthopedist's application to treat the various of backbone in recent years
Illness achieves preferable clinical effectiveness, has accumulated considerable experience.The purpose of spinal operation treatment is decompression, rebuilds just
Chang Xulie and Bony union, the advantage of interior fixation are that correction deformity, promote fusion, early rehabilitation.
There are fixed and universal two kinds of pedicle nails currently on the market, there is limitation in the selection face that doctor faces in the course of surgery
Property.
Utility model content
In order to overcome the shortcomings of that existing pedicle nail type is few, the utility model provides a kind of adjustable monoplane vertebra
Nut nail.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of adjustable monoplane pedicle nail,
Include: movable sleeve, nail, jackscrew and arc pitman, arc pitman is placed in movable sleeve U-type groove, is equipped with one in movable sleeve
Make nail that can only do the limited block of monoplane swing in movable sleeve, limited block is that anchor is connect with movable sleeve, has been broken on the market only
There is the fixed limitation with universal two kinds of pedicle nails.
Another embodiment according to the present utility model further comprises that the arc pitman is bonded limited block completely,
Jackscrew screws in movable sleeve and compresses arc pitman, and nail does spherical rotation relative to limited block, which can keep backbone not
With the consistency in two adjustable monoplane pedicle nail directions of segment, prevents pitman from generating and loosen and generate slide bar and show
As.
The utility model has the beneficial effects that increasing the type of pedicle nail in the market, the jail of pedicle nail is improved
Solidity.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of movable sleeve；
Fig. 3 is the structural schematic diagram of limited block；
Fig. 4 is the structural schematic diagram of nail；
Fig. 5 is the structural schematic diagram of jackscrew；
1. movable sleeve in figure, 2. limited blocks, 3. nails, 4. jackscrews, 5. arc pitmans.
Specific embodiment
If Fig. 1 is the structural schematic diagram of the utility model, a kind of adjustable monoplane pedicle nail, including movable sleeve 1, limit
Position block 2, nail 3, jackscrew 4 and arc pitman 5.
If Fig. 2 is the structural schematic diagram of movable sleeve 1, arc pitman 5 is placed in 1 top U-type groove of movable sleeve, for connecting
Each pedicle nail.
If Fig. 3 and Fig. 5 are the structural schematic diagram of limited block 2 and jackscrew 4 respectively, anchor is used between limited block 2 and movable sleeve 1
Connection, arc pitman 5 fitting limited block 2, jackscrew 4 completely screw in movable sleeve 1 and compress arc pitman 5, prevent arc from connecting
Stick 5 generates loosening.
If Fig. 4 is the structural schematic diagram for following closely 3, nail 3 is opposite with limited block 2 do spherical rotation and nail 3 limited block 2 effect
The rotation of monoplane can only be done down, which can not only keep the consistency in backbone different segment pedicle nail direction, prevent
Slide bar, and increase the type of pedicle nail in the market.
In surgical procedure, an osculum first is opened in pedicle of vertebral arch with passage-opening awl, then osculum is expanded with open device, then use silk
It attacks along osculum tapping to a certain extent, adjustable monoplane nail pedicle fix is lived with crow-bar, along having attacked
The screw way of silk screws in adjustable monoplane pedicle nail, and all pedicle nails are connected into finally by arc pitman 5
One can complete the fixed support of backbone.
